SHUTTLE TENSION.

Specification of Letters Patent. Patented Dec. 13, 1921.

Application filed September 3, 1921. Serial No. 498,355.

To all wkomz't may concern:

Be it known that we, Grorrm'nc D. Trims and J OI-IN H. STEIGER; citizens of the United States, residing at Paterson, in the county of Passaic and State of NewJersey, have invented certain new and useful Improvements in Shuttle Tensions, of which the following is a specification.

This invention relates to shuttles, and particularly to shuttles of the narrow-ware class, the principal objects being (1) to provide a shuttle with a tension means which will allow the wound package to rotate with perfect freedom, to deliver the filling, when the filling is subjected to draft but which will take up. any slack that tends to form and also hold the wound package stationary immediately the draft ceases, thus to insure the proper laying of the filling in the warp sheds and particularly to weave fabrics with perfectly formed edges, said tension means being so constructed that, as in replenishing the shuttle when the wound package becomes exhausted, said means will be proof against being distorted so as to fail to act properly and to provide for mounting the spindle on which the wound package is placed in such a way that while it may be readily released from the shuttle body, as for removing an empty quill and substituting a filled one, it will be securely locked in place when the shuttle is in use, thus to avoid any possibility of it at that time working out and causing injury to the warp.

In the drawing, 7

Figure 1 is a plan of one form of the improved shuttle;

Fig. 2 is a section on line 2-2, Fig. 1;

Figs. 3 and 4 illustrate the spindle-lock shown in Fig. 1, being sections on line 3, Fig. 1;

Fig. 5 is a section on line 55, Fig. 1;

Fig. 6 is a fragmentary plan of another form of the improved shuttle; and

Fig. 7 is a section on line -7, Fig. 6.

a designates the body of a shuttle, here of the usual bow type. At one side of and within the bow is suitably secured a plate I), which may be regarded as a part of the body or fixed part of the shuttle, the same having a socket 0 and horizontally alined with the socket an inwardly projecting boss d. Opposite the socket and at the other side of the bow is the usual notch e. f designates the spindle affording axial support for the quill g of the wound package g, the same being of a general form common in narrow ware shuttles, z. e., with one end f bent oil; when the other end is fitted into the socket end 7 may be slipped into the notch e, to be there retained in a way to be explained.

In the boss d is arranged the stem 72. of a fork h, which may be adjusted longitudinally therein and in a bore 2' and there held by a riveted pin adapted to penetrate any one of a series of holes in the stem and a corresponding hole in the boss. In this fork is pivoted a brake member is, its axis of movement being in a vertical plane. The brake member, is adapted to bear against the flat or square-cut end of the quill, and in order to admit or permit withdrawal of the spindle 7, which enetrates it, said brake member has a suitable recess 70' (Fig. 5)

which enters it from its upper edge, in reg istry with the plane, of movement (if the spindle. when assembling it with or removing it from the shuttle body. By adjusting the fork in the boss '03 quills of various lengths may be accommodated in the shuttle. In bores converging from thebase of the shuttle towardthe openin formed by its bow are arranged spiral springs Z Z suitably anchored at their outer ends and at their inner ends having attached thereto the thread guides or eyes m m. Guide or eye mis connected with the brake member by a light'cord or other flexible connection n which passes through a centrally located guide-or eye 0 preferablypivoted (aslby being wired) to the shuttle bow; through the medium of this cord the spring-pulled eye on normally tends to hold the brake member in braking contact with the end of the shuttle package, to wit, of quill g. Pivoted (as by being wired) to the shuttle bow. are two other thread guides or eyes 12 p arranged one on each side of the central fixed the brake member is relaxed, allowing the package to rotate freely on the spindle so as to deliver the filling, and when the draft ceases spring Z becomes immediately active again to subject the package to the braking action ofthebrake member.

Into the body of the shuttle so as to project into the notch 61 and in the same direction as the end 7 of the spindle, and also so as tolie in the same plane as the spindle moves-in entering it into and removing, it from the notch, is driven a stud r, the projecting end thereoi being canted toward the spindle and having its extremity at the side adjoining the spindle beveled oli. The stud is somewhat elastic and whenthe bent-off end of thespindle, its, other end being seated in the socket 0, is entered into notch c and forced againstvthe beveled or cam extremity of the stud the latter is sprung back and thereupon comes to bear frictionally against said bent-off end,so that the spindle is securely held in place and can only leave the notch ea when forced out by hand. v v

In the form shown in Figs; 6 and 7 the body'of'the shuttle includes an angular. metal frame 8 suitably secured in the bow opening, the oppositely arranged bent-of]? ends 8' 3 thereof reposing against thelsldes of said opening. Theend st has a socket t for the spindle a" and it has also a boss 1; to

' receive the stem to or thefork w in which the" brake member as, tobear against'the end of the quill 1 is pivoted, so much'ofthat form of our invention whichv is nowibeing described being the'same as that already dey scribedexcept for the frames and the means for adjusting stem a which in the present construction takes the form of aset-screw z tapped into the boss and bearing against the stem. The other bent-off end 8 overlies the notch'2 (corresponding to notch e) which receives the bent-oil endof the spintile and itself has an upwardly open notch On the end .9 is;

tures.

2 to receive the'spindle. fitted a sliding keeper 3 which is normally urged toward the extremity of'said end by aipl'ate-spring 4' secured to thevbase-portion of the frame 8 and has a recess 8 formed in its outer edge which is adapted to receive the spindle and coact-with the outer side of the notch 2 to retain the same in said notch, said outer side of the notch and the outer edge of the keeper being beveled so as to form a convergent approach 4' to the recess '3. When the spindle is entered into notch 2 and is forced into the approach 4; it cams back the keeper, which then springs back and securely holds the spindle until the keeper is again manually pressed back The outward limit of movement of the keeper is V on the spindle, said spindle being removable from said-structure transversely of itself and in a definite planeand the plate having a lateral notch opposite the spindle and reg 'istering with the plane ,in which the spindle is thus removable, and spring means for holding the plate against the package QQIn cOmbination, the body of a shuttle having a projecting'arm' anda: notch therein andalso a socket oppositethe notch, a spindle stepped in-the socket and tiltable therein into and out of the notchpand a slide on the arm normally spring-held in position to oppose tilting'movement of the spindle out otthe notch when the spindle is received therein.
